Abstract (en)
[origin: WO9745839A1] A data storage device comprises a controller and a semiconductor chip which includes a nonvolatile semiconductor memory having plural storage areas into each of which data is stored, a store instruction signal input terminal to which a store instruction signal is inputted, a storage controller for storing data into the semiconductor memory when receiving a store instruction signal through the store instruction signal input terminal, a read instruction signal input terminal to which a read instruction signal is inputted, and a read controller for sequentially specifying one of the storage areas in the semiconductor memory each time it receives a read instruction signal through the read instruction signal input terminal and then reading the data stored in the specified storage area. The controller includes a specifying data storage for storing specifying data that specifies one of the storage areas, a store instruction signal output circuit for outputting a store instruction signal to the store instruction signal input terminal of the semiconductor chip, and a read instruction signal output circuit for outputting a read instruction signal corresponding to the specifying data stored in the specifying data storage to the read instruction signal input terminal of the semiconductor chip.
